How to I get rid of the password on my Samsung S Health app?

A

AC Question

When I set up my Samsung S Health app, it asked to enter a password. I input some ridiculously long password, not realizing that every single time I opened the app, I'd have to enter it. Annoying when one wants to check one's mileage partway through a morning walk or hike.

How do I override the password or, better yet, get rid of it? I'd like to keep using this app - it's quite simple, and surprisingly accurate.

Oh, details: it's on a Samsung S4 phone, and I don't use any kind of an accessory with it (i.e.: Fit watch)
